When the increasing intensity and frequency of earthquakes in Northern Japan started to remind me of the foreshocks of the Loma Prieta Quake that hit the Santa Cruz, CA area in 1989, I started gathering earthquake intensity data from the Japan Meteorological Agency. A few days later--March 11, 2011--the earth's axis shifted when an off-the-scale quake jolted Northern Japan.
I continued to gather the data for a few days to monitor the intensity and frequency of the aftershocks, then compiled the data into an animation. Although the media tended to focus on a single major event (9.0 quake off the coast of northeastern Japan), this animation illustrates the disaster as a series of inter-related events over a brief period of time to show how patterns emerge from chaos to suggest predictability--something that you chaos theoreticians should be able to appreciate.
Note: Please accept my apologies for the six minute length of this animation; but, you will be watching the events of six days of quakes we experienced in northern Japan compressed into one-second increments. Otherwise, enjoy the bird's-eye view.
Here is the animation:
